摘要： A technique for calibrating a transceiver of a wireless communication device includes selectively coupling an output node of a transmitter of the transceiver to an input node of a receiver of the transceiver. A calibration signal is provided, from the output node of the transmitter, to the input node of the receiver. The calibration signal is down-converted, with the receiver, to provide a down-converted calibration signal. A discrete Fourier transform is performed on the down-converted calibration signal. Finally, one or more correction factors are determined based on an analysis of the discrete Fourier transform of the down-converted calibration signal. At least one of the correction factors is utilized to facilitate substantial cancellation of a direct current offset associated with the transceiver.

摘要： Spread spectrum packet-switching radio devices (22) are operated in two or more ad-hoc networks or pico-networks (19, 20, 21) that share frequency-hopping channel and time slots that may collide. The frequency hopping sequences (54) of two or more masters (25) are exchanged using identity codes, permitting the devices to anticipate collision time slots (52). Priorities are assigned to the simultaneously operating piconets (19, 20, 21) during collision slots (52), e.g., as a function of their message queue size or latency, or other factors. Lower priority devices may abstain from transmitting during predicted collision slots (52), and/or a higher priority device may employ enhanced transmission resources during those slots, such as higher error correction levels, or various combinations of abstinence and error correction may be applied. Collisions are avoided or the higher priority piconet (19, 20, 21) is made likely to prevail in a collision.

摘要： A comparator (231) for determining a peak number, representing a maximum or minimum of a set of numbers, includes a multi-element comparator (232) for comparing different pages of the set of numbers in a page comparison mode to output a candidate set of winning numbers, and for automatically switching to a leaf/tree search of the candidate set of winning numbers in an element comparison mode. Operating in parallel with the multi-element comparator (232), an index generation unit (233) processes flag/sign bits from the multi-element comparator in conjunction with state machine control logic (230) to keep track of the index/indices for the peak value. Upon completion of final stage, the index generation unit returns the absolute index (235) of the peak value.
